Resumo IPEN-doc 08518 Fotocalorimetria diferencial aplicada ao estudo da influencia de oxigenio na inibicao de reacoes induzidas por radiacao ultravioleta2002 - RUIZ, C.S.B.; MACHADO, L.D.B.; VOLPONI, J.E.Artigo IPEN-doc 10851 Accelerated weathering of UV/EB curable clearcoats2004 - RUIZ, C.S.B.; MACHADO, L.D.B.This study provides data regarding the behaviour of four UV- and EB-curable clearcoats - with or without light stabiliser additives - under accelerated weathering. The experimental data obtained from the weathered samples were evaluated and correlated to the formulation composition, type of radiation (UV or EB), radiation dose, and time in the ageing chamber. The results show that the EB-cured films have a better resistance to photoinduced weathering effects than do UV cured films. The UV/EB films with light stabilisers have shown greater stability than their counterparts with no additives. The ageing effects were evaluated by assessing parameters such as hardness, gloss, yellowness index, and changes in the Fourier transform infrared spectroscopy absorption bands.Artigo IPEN-doc 08857 Influencia da taxa de dose e da velocidade de processo na cura de revestimentos por radiacao UV/EB2002 - RUIZ, C.S.B.; MACHADO, L.D.B.Artigo IPEN-doc 09612 Influence of sample composition and processing parameters on the UV cure of clear coatings2002 - RUIZ, C.S.B.; MACHADO, L.D.B.; VOLPONI, J.E.; SEGURA PINO, E.Artigo IPEN-doc 08595 Characterization of a clear coating cured by UV/EB radiation2001 - RUIZ, C.S.B.; MACHADO, L.D.B.; SEGURA PINO, E.; SAMPA, M.H.O.Artigo IPEN-doc 07898 Cure degree estimation of photocurable coatings by DSC and differential photocalorimetry2000 - RUIZ, C.S.B.; MACHADO, L.D.B.; VANIN, J.A.; VOLPONI, J.E.Artigo IPEN-doc 09610 Oxygen inhibition and coating thickness effects on UV radiation curing of weatherfast clearcoats studied by photo-DSC2004 - RUIZ, C.S.B.; MACHADO, L.D.B.; VOLPONI, J.E.; SEGURA PINO, E.Artigo IPEN-doc 09611 Influence of sample composition and processing parameters on the UV cure of clear coatings2003 - RUIZ, C.S.B.; MACHADO, L.D.B.; VOLPONI, J.E.; SEGURA PINO, E.Artigo IPEN-doc 09186 Cure degree estimation of photocurable coatings by DSC and differential photocalorimetry2002 - RUIZ, C.S.B.; MACHADO, L.D.B.; VANIN, J.A.; VOLPONI, J.E.Artigo IPEN-doc 08596 Characterization of a clear coating cured by UV/EB radiation2002 - RUIZ, C.S.B.; MACHADO, L.D.B.; SEGURA PINO, E.; SAMPA, M.H.O.
